We tested whether maternal energy supplementation during the last third of gestation improves birth weight, neonatal wellbeing, and mother-young bonding. Thirty-six pregnant French Alpine goats were randomly allocated among three nutritional treatments for the last third of pregnancy: (i) Control, fed alfalfa (T-0; = 12); (ii) alfalfa + 150 g/head daily energy concentrate (T-150; = 12); (iii) alfalfa + 300 g/head daily energy concentrate (T-300; = 12). At birth, we collected progeny data on birth weight, birth type, sex, rectal temperature, heart rate, respiratory rate, time to standing, time to udder connection, and time to first feeding. For the dams, we collected data on the duration of labor, time to clean the progeny, and time to allow first suckling. At birth, body weight, rectal temperature, heart rate, and the respiratory rate did not differ among treatments ( > 0.05). In the dams, labor duration was not affected by the treatments ( > 0.05). The T-150 dams were faster to clean the newborn and allow first suckling ( < 0.05). The T-150 progeny were faster to stand and the T-300 progeny were faster to connect to the udder ( < 0.05). We conclude that energy supplementation of the dam during the last third of gestation does not affect the birth weight of the progeny, but enhances the mother-young bonding.
